cheering for the Utes. Which is totally fine, just don't hate on the team or school that represents your faith, IMO, and many of them do. I'll never understand it. We're all "on the same team" so to speak with God. I know Utes hate to hear that, but you can't listen to the prophets talk about BYU and not get the message that BYU plays an important role in the kingdom.
Cheer how you want on Saturday afternoon, but every member of the church should be hoping for BYU to be successful in its divinely appointed mission.
